Answer

cost = $724.90

Work Step by Step

First, find the equation that you all need to use to solve.
There will be a set 49.95 dollar fee.
There will be a 1.19 dollar fee per mile driven, and a 3.89 dollar charge per gallon for gas, and the truck gets 18 miles per gallon.
Using x to represent the number of miles, the equation will be:
$1.19x+ 3.89 (x\div18) + 49.95= cost$
Next, solve for the number of miles, by translating using the map.
3.25 inches + 1.75 inches = 5 inches
96 miles = one inch, so 5 inches = 480 miles.
From there, solve the equation:
$1.19x+ 3.89 (x\div18) + 49.95= cost$
substitute 480 for x
$1.19(480)+ 3.89 (480\div18) + 49.95= cost$
divide
$1.19(480)+ 3.89 (26.67) + 49.95= cost$
multiply
$571.2+ 103.75 + 49.95= cost$
add
cost = $724.90
